Because less energy is required and less heat is generated, you don\u2019t need as much cooling, which means you can use smaller heat sinks \u2013 Porsche claims it can make them 20 per cent lighter and also make passive components smaller, thus reducing the size and weight of your amplifier.<\/p>\n
One of the biggest challenges for car audio engineers is always the system packaging and being able to make the most of the available space in the car, and this seems to be a convenient way of adding extra versatility without sacrificing performance.<\/p>\n
Because less aluminium is used, less heat is generated during the manufacturing process, which has the knock-on effect of reducing CO\u2082 emissions during amplifier production, so it\u2019s good news from an eco perspective, too.<\/p>\n
There’s no word on which cars will be the first to feature the tech, but Porsche has confirmed that gallium nitride for Burmester High-End Sound will enter series production and make its debut “in a future Porsche vehicle in 2027”.<\/p>\n
